X-ray scattering by thermally populated phonons in crystals gives rise to thermal diffuse scattering (TDS). Measurements of TDS intensities as functions of momentum transfer and sample temperature can provide valuable information about the bonding of the crystal lattice, including phonon dispersion relations and interatomic forces. This method has a ...
